The distribution and sources of EMPs produced at Shenguang-Ⅱ(SG-Ⅱ)series laser facilities are systematically investigated.The results indicate that the EMP amplitudes in the SG-Ⅱ ps PW laser are very strong,one order higher than those from the SG-Ⅱ laser facility.EMPs outside the target chamber decrease exponentially with the distance from the measuring points to the target chamber center at the two laser facilities.Moreover,EMPs can be remarkably reduced when the picosecond laser together with the nanosecond laser is incident to targets compared to the SG-Ⅱps PW laser alone.The resulting conclusions are expected to offer experimental supports for further effective EMPs shielding design and achievement in high-power laser facilities.

分支河流体系(DFS)是基于对全球700余个现代沉积盆地中冲积河流沉积体系进行统计分析基础上提出的新术语,它是指河流从某一顶点开始进入盆地并呈放射状展布的沉积体系.通过梳理10 a来相关学者对全球范围内现代及岩石记录中DFS的研究成果,介绍了分支河流体系的概念、规模、特征等方面的研究现状.结果表明DFS的形态和分布是构造和气候共同作用的产物,其中构造活动是DFS发育的前提和决定性因素;DFS研究应注重其近端、中段、远端在时间和空间上的连接关系,以建立DFS沉积模式;最后总结了 DFS的研究技术和方法.分支
Taking the shale of Shuijingtuo Formation of Lower Cambrian in Yichang area as the research object,the shale reservoir characteristics are comprehensively evaluated and classified by fitting regression and formula calculation method in this study,using la
To explore AC-DBD\'s ability in controlling dynamic stall,a practical SC-1095 airfoil of a helicopter was selected,and systematic wind tunnel experiments were carried out through direct aerodynamic measurements.The effectiveness of dynamic stall control
The classical prompt loss of fast ions produced by minority ion cyclotron resonance heating(ICRH)is studied by a guiding center orbit following code in the Experimental Advanced Superconducting Tokamak(EAST).It is found that the loss of fast ions produced
The formation of homogeneous dielectric barrier discharge(DBD)in air is a key scientific problem and core technical problem to be solved for the application of plasmas.Here,we report the effect of two-dimensional(2D)nanomaterial Ti3C2Tx(Tx=-F,-O and/or-OH
This work treats the Al2O3-ER sample surface using dielectric barrier discharge fluorination(DBD-F),DBD silicon deposition(DBD-Si),atmospheric-pressure plasma jet fluorination(APPJ-F)and APPJ silicon deposition(APPJ-Si).By comparing the surface morphology
It is recognized that standing wave effects appearing in large-area,very-high-frequency capacitively coupled plasma(CCP)reactors cause center-high plasma non-uniformity.Using a high-frequency magnetic probe,we present a direct experimental diagnostic of t

To compensate for the shortcomings of the thermal and catalytic regeneration of the diesel particulate filter(DPF),a self-designed packed-bed dielectric barrier discharge(DBD)reactor for DPF regeneration was developed.The DBD reactor with the main active
There are widespread Mesozoic-Cenozoic terrestrial volcanic activities in East China,and they produced favorable geologic factors for the volcanic reservoirs.To reveal the spatio-temporal evo-lution of regional volcanisms and their tectonic setting,we sub
